No. 139,154 1 Claim. (Cl. 98-42) This invention relates to new and useful improvements 1n a boat ventilator adapted to be installed in the outer wall or deck of a boat or the like to provide light at all times and air when desired, in an enclosed room therein, such as the rest room, and this application is a continuat1on in-part of my copending application filed July 19, 1960, Serial Number 43,911, now Patent No. 3,031,943.

A principal object of the present invention is to provlde a boat ventilator that gives complete ventilation, is rain and spray proof and is fully screened to keep out all foreign matter, insects and the like.

Other objects of the invention are to provide a boat ventilator that can be formed of colored plastic material for protecting the eyes from the suns rays; and that can be easily manipulated from the inside of the boat.

A further object is to provide a boat ventilator that is simple in construction, economical to manufacture and highly efficient for the purposes intended.

For further comprehension of the invention, and of the objects and advantages thereof, reference will be had to the following description and accompanying drawings, and to the appended claim in which the various novel features of the invention are more particularly set forth.

In the accompanying drawings forming a material part of this disclosure:

FIG. 1 is a side elevational View of a boat ventilator embodying my invention shown applied to a boat.

FIG. 2 is a top plan view of the boat ventilator.

FIG. 3 is a sectional view taken on the line 33 of FIG. 2.

FIG. 4 is a disassembled side elevational view of the boat ventilator.

FIG. 5 is a top ventilator.

:FIG. 6 is a invention.

FIG. 7 is a invention.

FIG. 8 is a top plan view of the part of the invention.

Referring in detail to the drawings, a boat ventilator embodying the invention is shown in FIG. 1 and designated generally by the reference numeral 10. The ventilator 10 is shown mounted over a circular opening 12 in the hood 14 of a boat.

The ventilator comprises a hollow cylindrical tapering body 16,.open top and bottom, with an integral flange 18 around the base thereof. The body 16 is shown disposed over the opening 12 in the boat with the flange 18 secured in position on the hood 14 by means of plastic screws 20 passing through holes 22 in the flange 18 and plastic nuts 24. The body 16 is formed of transparent plastic material.

In accordance with the invention, means is provided for selectively and adjustably closing and opening the top opening in the body 16. For this purpose, a transparent plastic ring 26 having a flat crosspiece 28 with a central hole 30 therein is secured to the top edge of the body 16 by adhesive or the like. A circular screen 32 with a central opening 34 therein is fastened to the bottom surface of the ring as seen in FIGS. 3 and 4. A threaded nut 36 is welded to the undersurface of the ring 26 and is disposed around the hole 30 therein. A movable transparent plastic cover plate 40 having a downwardly curved peripheral edge 42 is placed over the ring 26. A threaded perspective view of the body of the plan view of the ring forming part of the plan View of the screen forming part of the cover plate forming nut 44 is suitably secured to the undersurface of plate 40 at its center.

A headed screw 46 extends through the nut 36, the opening 34 in screen 32, hole 30 in ring 26 and through nut 44 with its free end jammed against the undersurface of cover plate 40. The head 48 of the screw is accessible through the bottom opening of body 16.

In operation of the ventilator, by turning the head 48 of the screw 46 in one direction, clockwise as viewed in FIG. 3 for example, the cover plate 40 will be moved away from the top surface of the ring 26, permitting air to enter over the protruding peripheral edge 49 of the ring 26 and the cover plate 40, through the ring 26, screen 32, hollow body 16 and opening 12 in the hood 14 of the boat to the interior room in the boat for ventilating the room. The air passes through the screen 32 so that all foreign matter such as dirt, insects, etc., is kept out of the room.

By turning the head 48 of the screw 46 in the opposite direction, that is counterclockwise as viewed in FIG. 3, the cover plate 40 will be moved toward the ring 26 and seated on the ring forming a seal at this point thereby preventing passage of air into the room.

An important feature of the invention is the protruding peripheral edge 49 of the ring 26 beyond the top edge of the 'body 16. By reason of this protruding edge, any moisture, water and the like drawn in by the air will lash against this protruding edge and will be thrown back thereby preventing its entry into the room.

The invention also contemplates protecting the body 16 and cover plate 40 from the weather and rough seas and for this purpose a transparent colored plastic domeshaped cover 50 is provided. The dome-shaped cover has a semi-elliptical body 52 terminating at its periphery in a flat annular flange 54. The flange 54 is provided with spaced holes 56 spaced similarly to the spacing of the holes 22 in the flange 18 of the body 16. When the domeshaped cover 50 is in operative position over the body 16 and plate 40, the holes 56 and 22 are in alignment and the screws 20 are passed through the aligned holes, spacing sleeves 58 of plastic having first been sleeved over the screws between the flange 54 of the dome-shaped cover 50 and the flange 18 of the body 16 to space the flange of the dome-shaped cover away from the flange of the body to provide a passage 60 for the air to enter and circulate. The screws 20 fasten the dome-shaped cover 50 and body 16 in position on the hood 12.

When the dome-shaped cover is in position as shown in FIG. 1, the air enters passage 60 between the flange 18 of body 16 and the dome-shaped cover 50 and circulates around the tapering body 16 and when the cover plate 40 is in open position, the air enters underneath the plate and inwardly through the ring 26, screen 32, body 16 and opening 12 in the hood 14 into the room in the boat. The transparent colored dome-shaped cover 50 permits light rays to enter into the room to illuminate the room but protects the eyes of the occupants from danger from the suns rays.

While I have illustrated and described the preferred embodiment of my invention, it is to be understood that I do not limit myself to the precise construction herein disclosed and that various changes and modifications may be made within the scope of the invention as defined in the appended claim.

Having thus described my invention, what I claim as new, and desire to secure by United States Letters Patent 1s:

A boat ventilator comprising a hollow cylindrical transparent plastic body, open top and bottom, tapering outwardly from top to bottom, adapted to be secured to the hood of a boat over an opening in said hood, a ring secured to the open top edge of said hollow cylindrical body, said ring having a erosspiece thereacross with a central hole therein, a nut Welded to the undersurface of the crosspiece of said ring, an imperforate movable cover plate adapted to seat on the ring, a nut on the undcrsurface of said cover plate at its center, said nut serving as a bearing member, a headed screw member extending through the nut on said crosspiece, the hole in said crosspiece and having its free end secured to the bearing member on the undersurface of said cover plate whereby turning of said screw member in one direction moves the cover plate away from the ring and turning in the opposite direction moves the cover plate toward and onto the ring, a screen secured to the undersurface of the ring and across the top opening in the hollow cylindrical body, said hollow cylindrical body having a peripheral flange therearound, a dome-shaped body of colored plastic surrounding the cover plate, ring, screen and upper portion of the hollow cylindrical body, an annular flange on the dome-shaped body disposed over the flange on said hollow cylindrical body in spaced relation thereto, and screw means for fastening the flanges together in spaced relation.
